Standardization of communication between Uncrewed Aerial Vehicle (UAV) and UAV or UAV controller using 5G System (5GS) is being promoted. Meanwhile, regarding direct communication (direct C2 communication) between the UAV and UAV controller, a method of releasing after establishing a communication path or behavior when authentication and/or approval is canceled are not clearly defined. When User Equipment (UE) that has established a communication path for direct C2 communication receives a PDU session release command message or a PDU session change command message from the network to cancel authentication and/or approval of the communication path for direct C2 communication, the UE can indicate an appropriate reason value in a procedure for releasing the communication path for direct C2 communication.

    [과제] 5GS(5G System)를 이용한 UAV(Uncrewed Aerial Vehicle)와 UAV, 또는 UAV controller와의 통신의 규격화가 추진되고 있다. 한편, 그 UAV와 UAV controller의 직접 통신(다이렉트 C2 커뮤니케이션)에 대해, 통신로를 확립한 후의 해방 방법이나 인증 및/또는 승인이 취소되었을 때의 거동이 명확하게 되어 있지 않다. [해결 수단] 다이렉트 C2 커뮤니케이션을 위한 통신로를 확립해 있는 User Equipment (UE)는 네트워크로부터 다이렉트 C2 커뮤니케이션을 위한 통신로의 인증 및/또는 승인을 취소하기 위한 PDU 세션 해방 커맨드 메시지, 또는 PDU 세션 변경 커맨드 메시지를 수신한 경우, 다이렉트 C2 커뮤니케이션을 위한 통신로의 해방 수속에서 적절한 이유값을 나타낼 수 있다.
